The PlayStation 4 will not use Sony's Cell processor, nor any advancement of the technology, industry sources have told gaming blog Kotaku.
As of press time, Sony had not responded to GameSpot's request for comment.
The Cell processor (at right) was at the heart of the PlayStation 3, helping the system render its high-definition visuals and other complex processes. However, in 2007, Sony abandoned future Cell development based on its high cost.
As for the PS4, Sony acknowledged its existence last year, but gamers shouldn't expect it anytime soon. Sony has shot down rumors that the system would be unveiled at the 2012 Electronic Entertainment Expo this June, later saying news of a PS4 in 2012 would be distracting.
